Revealed: Trooping the Colour candid moments the Palace didn't want caught by the cameras last year

Last year, Trooping the Colour was full of smiles, laughter and chaos but also moments the royal family would perhaps prefer to forget. 

While the day is centred around marking the official birthday of the British Sovereign and the display of military precision, the Prince and Princess of Wales' children stole the show with their playful antics. 

Prince Louis, six, Princess Charlotte, nine, and Prince George, ten, are known to cause quite a stir at big events. 

Their behaviour during their parade from Buckingham Palace to Whitehall was the main talking point of the day, with royal fans in stitches from watching the trio.

One of the main highlights of the previous Trooping the Colour is when Louis was in a carriage with his siblings and visibly held his nose and scrunched up his face as a reaction to a strong smell of horse manure

Kate and William's youngest child, Prince Louis, is known for his cheeky personality and also for stealing the limelight at events. 

Last year, he was particularly expressive on the Buckingham Palace balcony, pulling faces and playing up to the camera. 

Despite more than 1,400 parading soldiers, 200 horses, 400 musicians and a flyover of 70 aircraft, Louis was the star of the historic day.

Fans were delighted to see his signature 'window wiper wave' during the appearance, where he was spotted doing a small dance, as well as a military-style salute.

Later on the balcony, Louis was seen saluting as he waved at crowds to celebrate the Trooping the Colour parade. 

The adorable royal was also seen throwing his fists in the air and pouting as his mother Kate looked at him with pride and amusement. 

One of the main highlights of the flypast above Buckingham Palace saw 18 Typhoon fighter jets spelling out the King's monogram 'CR' - short for Charles Rex.

As the planes zoomed overhead Kate encouraged Prince George to wave to the crowds as she smoothed down Prince Louis' hair and urged him to face the crowd.

It's also thought that Princess Charlotte was 'getting impatient' during a conversation with Sophie, Duchess of Edinburgh, according to the Mirror.

Lip reader Jeremy Freeman suggested she was asking how long the event would last, according to the outlet.

One of the main highlights of the previous Trooping the Colour is when Louis was in a carriage with his siblings and visibly held his nose and scrunched up his face as a reaction to a strong smell of horse manure.

Riding through the Mall, the young royal found it hard to hide his reaction to the stench and his older brother George - who is due to be King after his father - was also snapped wrinkling his nose.

The children were accompanied by the Princess of Wales and Queen Camilla, but that did not stop their strong facial expressions. 

Charlotte, Louis and George were allegedly given a stern telling off by their mother Kate during the carriage journey. 

On their way to the palace, lip reader Jeremy claimed she said: 'Do not look behind whilst on the coach.' 

But her daughter, Princess Charlotte, was spotted looking back almost immediately after the warning was given. 

The Princess of Wales - who has been out of the spotlight as she undergoes preventative chemotherapy, missed the Colonel's Review, the traditional rehearsal for Trooping the Colour, last Saturday. 

Royal expert, Katie Nicholl, told ET that it is likely that she will not be attending the annual event on Saturday. 

Katie said: 'She has made it very clear that she wants to stay out of the spotlight. She needs this period and is below the radar for her recovery. We're so used to seeing her up on that balcony.'
